Abstract
Background and Objectives: Serotonin transporter (5-HTT) gene allelic variants were shown to be associated with Neuroticism and Harm Avoidance but the results were not replicated in other studies. The current investigation was undertaken in a further attempt to study the relationship between 5-HTT polymorphism and personality traits.
Subjects and Methods: To evaluate a spectrum of personality traits, MMPI was administered to a sample including patients with affective disorders (n=114), patients with schizophrenia spectrum illnesses (n=110) and psychiatrically well controls (n=124). All groups were genotyped for VNTR-17 and functional insertion-deletion (5-HTTLPR) polymorphisms.
Results: An association was found between 5-HTTLPR polymorphism and scores on three MMPI scales: Psychopathic deviance, Paranoia and Schizophrenia in patients with affective disorders and Schizophrenia in normal subjects. Both affected and control individuals with ‘ss’ genotype exhibited lower scores on these scales.
Conclusion: We demonstrated that functional deletion/insertion allelic variation associated with decreased expression of serotonin transporter (‘s’ allele or ‘ss’ genotype) may restrict expression of schizoid traits in normal subjects and patients with affective disorders.
